Most of HEV are built using existing engines. These engines have been developed for conventional car and are not especially tailored for HEV. The objectives of this work are to establish general requirements placed on an ICE for a HEV application, to draw the main characteristics of the engine and to find the best configuration of twin-cylinder ICE to motorize an HEV. The twin-cylinder engine offer interesting perspectives in the field of HEV thanks to its small size, low weight and low cost. [less ▲]

Abstract : Poles of competitiveness were launched in Walloon region as a policy for innovation support. This policy aims to reinforce cooperation and partnering between industry and research universities in the region: critical mass, excellence, international size should be reached through the construction of large cooperative projects. Thes new dynamics were in line with the earlier ones which were developed as separate branches of research policy for universities and firms. The governance of the poles, largely controlled by the firms representatives, promoted the development of new forms of interactions between the institutional segments of the Triple Helix of innovation: state – industry – university. Universities stepped quickly in the poles dynamics and took advantage of the opportunity to reinforce their presence in the regional economic framework. Administration was not associated to the launch of the government-defined process and encountered difficulties stepping in the process and entering into these new modes of governance, more supportive than normative. The innovation model at the basis of the policy initiative sets a strong systemic stance to the dynamics of knowledge production but fails to deliver enough reflexivity to go beyond the narrow instrumental rationality of innovation.

Mon intention est de revenir sur un aspect tout à fait particulier du débat entre la phénoménologie et la psychologie de Natorp, à savoir l’écart entre une théorie « statique » et une théorie « génétique » des essences (eidè) ou, pour reprendre l’expression de Natorp, entre un « platonisme statique » et un « platonisme génétique ». Avec cette opposition en tête, j'examine le contentieux qui oppose Reinach à Natorp, à partir de la recension de la "Psychologie générale" rédigée par Reinach. Je focalise mon attention sur les thèses natorpiennes suivantes: (1) Le Je pur est inobjectivable et ne peut être décrit – à quoi Reinach objecte que le Je pur est une donnée phénoménologique, un phänomenologischer Befund; (2) La distinction entre acte et contenu est relative – à quoi Reinach objecte qu’elle est absolue; (3) La distinction entre contenu et objet est également relative – à quoi Reinach objecte que cette distinction est utilisée de façon équivoque mais doit être entendue comme absolue en un sens au moins.

In opposition to traditional machining in which part is manufactured by material removal, rapid prototyping techniques allow parts manufacturing by material addition. The part is built layer-by-layer and the sum of all layers creates the part. Currently, several techniques exist. They use different kind of materials (metals, ceramics, polymers) and technologies (laser melting, laser polymerising, 3D-printing, cladding, ...). Some of these techniques can deal with nanometric particles. In the case of which a near net shape part is built and must be sintered after shaping, the addition of nano-particles can be useful for sintering by increasing specific surface and reactivity of the batch or by improving the properties of the material. An overview about techniques of rapid prototyping allowing the processing of nanomaterials will be discussed. Tests have been done using Optoform process. This process uses a laser to polymerize a paste made of photo-curable resin loaded with powdered material. Nano-particles can be added and stabilized in the paste. In this presentation, the results obtained with both systems Al2O3 + nano Zr02 and SiC + Nano SiC will be discussed. [less ▲]

The main source of atmospheric mineral dust is the Sahara and its desertified margins that produce about half of the yearly global mineral dust. Saharan dust is often transported far away to the sources and causes air quality deterioration impacting northwards the Mediterranean and Europe, westwards crossing the Atlantic Ocean to the United States, the Caribbean and South America, and southwards to the Gulf of Guinea. Saharan dust storms can lead to particulate levels that exceed internationally recommended levels and transport allergens, including bacteria and fungi. Therefore special attention is paid to dust storms as such mineral particulate matter air pollution may be a serious health threat in various regions of the world because it may promote respiratory infection, cardiovascular disease and other ailments.

Simbol-X is a mission initially driven by the French and Italian space agencies. This is a formation flying satellite whose main interest is an unprecedented imaging and spectral capability, with a high sensitivity at energies between 10 and 80 keV. This space observatory is especially designed to study acceleration processes in astrophysical sources, along with extreme physics under relativistic conditions. I will briefly present the current status of the mission. I will also discuss prospects for future observations of massive stars with Simbol-X, aiming at probing the physics of particle acceleration in colliding-wind massive binaries. [less ▲]

In various species a relationship between oocyte maturity and morphological characteristics of oocytes has been established. To our knowledge, immature oocyte aspect under light microscopy has been paid little attention in the equine. The aim of the study is to give a general description and analyse microscopic parameters of immature oocytes. Follicles from abattoir ovaries are punctured after measurement of their diameter and their cumulus-oocyte complexes are recovered. Different characters such as oocyte diameter, cumulus aspect, granulosity and polarity of ooplasm are observed under light microscopy. No correlation between estral activity, follicle maturity, cumulus cells aspect, polarity and granulosity of ooplasm was observed. Thickness of zona pellucida differs between oocytes with polar or non polar ooplasm. No correlation was observed between follicle diameter and oocyte diameter and none of the other studied parameters showed an influence on oocyte diameter. Results show that no character of oocytes observed under light microscopy can be related to follicular origin or to any other character. Further studies have to be done to compare these immature oocytes with mature oocytes and to find the ultra-structural origin of characters observed under light microscopy. [less ▲]

Deux caractéristiques importantes de l’investissement en exploration ou production pétrolière sont les montants financiers très importants en jeu et les incertitudes élevées. Pour ces raisons, l’analyse du risque devrait être mise en oeuvre dans le processus d’évaluation et de sélection des projets. En fonction de leurs ressources disponibles, les compagnies pétrolières sélectionnent un ensemble de projets sur la base de certains critères : la valeur actuelle nette, le taux de rendement interne, l’indice de profitabilité, etc . . . Cependant, ces critères se révèlent insuffisants vu, d’une part, l’absence de la notion du risque qui est un élément essentiel de l’industrie pétrolière, et d’autre part, l’omission des interactions entre les différents projets. Dans ce travail, afin de pallier aux insuffisances de l’approche traditionnelle, nous appliquons une variante de la méthode de Markowitz afin de déterminer le portefeuille optimal de projets d’exploration ou production qui assure le meilleur compromis risque minimum-rendement maximun sous les diverses contraintes auxquelles l’entreprise est confrontée. Un cas pratique d’application de cette méthode à la sélection de projets d’exploitation pétrolière en Mer du Nord est présenté. Ce cas pratique permet d’illustrer l’influence du facteur prix du brut sur le choix du portefeuille. [less ▲]

L’exploration et le développement d’un champ pétrolier font face à de nom- breuses incertitudes liées aux rendements et aux coûts tout au long du cycle de vie du pro jet. A titre d’exemple les réserves, les investissements, les coûts opératoires, la production et le prix du pétrole sont souvent incertains. En conséquence, Il difficile de prévoir les cash-flows même pour les pro jets pétroliers les plus simples. Différentes méthodes sont disponibles pour aider les décideurs à évaluer les incertitudes, et réduire le risque des opportunités d’investissement en amont pétrolier. La simulation a été reconnue comme un outil d’analyse de risque et de prise de décision en évaluation de pro jets d’investissement en amont pétrolier au début des années 60. Aujourd’hui pra- tiquement toutes les grandes compagnies pétrolières ont incorporé la simulation dans leurs études de pro jets. Dans cet article, nous essayons d’expliquer les critères d’évalua- tion et d’analyse du risque de pro jets d’investissement en amont pétrolier basés sur les cash-flows et de montrer comment la simulation de Monte Carlo peut être utile dans ce cadre.

Two important characteristics of petroleum exploration and production investment are the high nancial amounts and uncertainties. For these rea- sons, the risk analysis should be implemented in the projects evaluation and the selection process. Depending on their available resources, petroleum companies choose a number of projects on the basis of some criteria: the net present value, internal rate of return, pro tability index However, these criteria appear to be insu cient if we consider, on the one hand, the ab- sence of risk idea which is an essential element of the petroleum industry, on the other hand the omission of the correlations and interactions between di erent projects. In this paper, in order to make up for the lacks of the traditional approach, we apply a variant of Markowitzs method to deter- mine the e cient portfolio exploration and production projects that insure the best compromise minimum risk-maximum return under the di erent constraints faced by the company. A practical application of this method about selection of petroleum exploration projects in the North Sea is pre- sented. This practical case illustrates the in uence of the crude price in the choice of the portfolio. [less ▲]

The B1.5 II-III star HD 180642 is the only known Beta Cephei star in CoRoT’s core programme. To complement the space data of this target, both ground-based photometric and spectroscopic data were collected, to which we added several archival observations. In this talk, we describe our results from a full integration of CoRoT and intensive ground-based observations. The star is a non-linear dominant radial mode pulsator for which low-amplitude modes are detected for the fi rst time. A few of the latter are observed in our ground-based datasets so that a mode identifi cation for them is possible. To this end state-of-the-art techniques are adapted to be applied to a star with a highly non-linear behaviour of the radial mode. Additionally, a careful interpretation of the CoRoT lightcurve helps to identify the wavenumbers. Besides this outcome, the Van Hoof effect for the dominant mode is investigated and the stellar parameters and chemical abundances are determined. All this information is to be used as additional constraints to the CoRoT pulsation frequencies, for asteroseismic modelling of this Beta Cephei star. Additional abstracts cover the lightcurve modelling of this pulsator (Degroote et al.) as well as seismic modelling (Thoul et al.). [less ▲]

The Vocontian Basin of SE France was formed along the northwestern border of Tethys during Mesozoic times. Mainly known for its rich ammonite fauna, this basin has also yielded Jurassic and Cretaceous ichthyosaur fossils. The specimens discussed here were discovered in lower Toarcian limestone and marl successions in the vicinity of Digne-les-Bains, High-Provence Alps. One of best-preserved specimens is identified as Suevoleviathan sp., a relatively rare genus previously reported only in the German basins. The specimen is fairly complete but crushed and embedded in limestone from the Falciferum ammonite zone. Because the skull is too damaged to see bone sutures, assignation to this genus is mostly based on fin and coracoid morphology. Along with this specimen, a premaxilla and paddle elements of Eurhinosaurus longirostris and possible Stenopterygiidae centra were found in nearby black marls of the Exaratum ammonite subzone (Falciferum zone, Lower Toarcian; see Floquet et al., 2003 for a detailed stratigraphy). These soft marls were deposited in anoxic waters and are coeval with the Posidonia shales of southwest Germany, the Jet rock formation of northeast England and Grandcourt shales of Luxembourg, which allows faunal comparisons between these basins. The localities from the Vocontian Basin are closer to the Tethys than other sites where Toarcian identifiable ichthyosaurs have been found in Europe. Nevertheless all identifiable specimens from the Vocontian Basin are also identified in other basins across Europe. It suggests that Toarcian ichthyosaurs had wide palaeogeographical distributions and were highly mobile swimmers, perfectly adapted to open marine environments. [less ▲]

The use of Lattice Boltzmann (LB) methods is interesting to describe flows through complex geometries encountered in Chemical Engineering (porous media, packed beds, multi phase flows). However, flow simulations based on LB methods can require big amounts of memory. It is not always possible to run a simulation on a single machine. Distributed computing is a solution to this problem and also accelerates the execution of the flow simulation. In the context of dynamic heterogeneous clusters, the available machines can have different computational powers. The computational power of each machine can vary during a flow simulation (because of background load). Also, the number of available machines can change. These characteristics impose the use of special technics. Dynamic Load Balancing allows the optimal use of available machines. A fault occurs when one or several machines interrupt the execution of the distributed software component they were executing. Checkpointing makes the system fault tolerant. In order to obtain a scalable software and to suppress single points of failure, a special effort is made to decentralize as much as possible the software components of the simulator. Currently, fluid flows of 400³ points (more than 9 GBytes of data) are simulated using an heterogeneous cluster of 54 machines. [less ▲]

Cette communication portera sur une approche évaluative du développement professionnel de futurs formateurs d’enseignants (FF). Dans le cadre d’un module de formation du master en Sciences de l’Education de l’université de Liège (ULg – Belgique), ceux-ci sont préparés à accompagner professionnellement de futurs enseignants (FE) selon une démarche de « supervision réflexive » (Beckers, 2007) inspirée des travaux de Schön (1983) et de Vermersch (1994, 2004) et complétée par l’apport de la didactique professionnelle (Pastré 2005, 2008 ). Il s’agit à la fois de maximiser les occasions pour le FE de prendre conscience de son modèle opératif en situation professionnelle et d’augmenter l’adéquation de son action par meilleure appréhension de la structure conceptuelle de ces situations en regard des buts prioritaires du métier. Cette compétence est à la fois travaillée à l’ULg (en séances collectives, individuelles et en petits groupes) et sur le terrain où les FF accompagnent les FE en stage (cette année, en classes préscolaires). Le travail théorique et pratique de la démarche de supervision réflexive avec les futurs formateurs a débouché sur la clarification de critères de qualité de l’accompagnement visé. Ceux-ci sont appliqués par les formateurs ULg aux données brutes de l’ accompagnement mené par chaque FF (traces retranscrites des entretiens de régulation et rédaction du carnet de bord). Ils sont également utilisés en auto-évaluation par les FF à propos de leur accompagnement. Cette double démarche d’évaluation (hétéro-évaluation et auto-évaluation) alimente une partie de la séance de « confrontation herméneutique » qui réunit chaque FF et les deux formateurs ULg après lecture par ceux-ci de tous les documents (données brutes et rapports). Cette partie du travail permet d’approcher le degré d’appropriation de la compétence d’accompagnement par le FF (genèse instrumentale et conceptuelle – Pastré, 2005). Chaque FF produit également un rapport qui porte sur l’analyse de l’accompagnement qu’il a mené, en interaction avec les caractéristiques contextuelles, et sur l’évolution qu’il a pu observer chez son compagnon FE du point du développement de ses compétences professionnelles et de sa construction identitaire. La discussion de ces analyses alimente la deuxième partie de la « confrontation herméneutique » ; elle permet d’approcher davantage une éventuelle genèse identitaire (Pastré, 2005). L’analyse critique de ces multiples sources d’information et la triangulation des données alimentera la réflexion sur la pertinence des outils et des démarches d’évaluation de ces processus complexes que sont le développement des compétences et de l’identité professionnelles.
